Forensic Applications

Some forensic applications for automation are driven by laborious and lengthy extraction processes before the GC or LC analysis takes place. Turn around time in a crime lab or a contract lab are important therefore speed and walk away convenience is important. Blood alcohol GC methods performed in Police departments should be push button for the blood analysis. Very often versatility is the most important feature. Often the samples are solids which can be analyzed by outgasing of the fire propellant or any other chemical fingerprint. Headspace GC helps finding the needle in the hay stack. Having a COMBI PAL which quickly changes from liquid to headspace injector becomes a bargain.

Special liquid-liquid extractions, filtration, SPE, SPME and pre-concentrating steps help sorting out the analytes of interest before the are analyzed.
